Hi there — a journal by
Ertugrul Sagdic a software engineer from Istanbul.
I build software with a passion to make a meaningful impact with every line of code. My engineering journey is defined by pushing boundaries in research, progress, and continuous improvement.
More about me
From the vibrant streets of Istanbul to the scholarly corridors of Lamar University in Texas, my software engineering journey is marked by a relentless pursuit of knowledge and innovation. Holding a Bachelor’s degree in Computer Science from Marmara University and Master’s at Lamar University, I am deeply committed to advancing in technology and software development.
Away from the keyboard, you might find me delving into the latest tech trends, lifting weights at the gym, enjoying a good book, or unwinding with my favorite TV shows. I believe in maintaining a balanced life to fuel creativity and innovation.
Throughout my career, I've navigated through diverse roles that have each contributed to my development:
Mobile Application Development: Engineered intuitive mobile interfaces to enhance user experience and functionality.
Full Stack Web Application Development: As a key full-stack engineer, I engineered theContinuous Improvement Softwareproject using Node JS and React JS to automate suggestion, kaizen, and near-miss workflows, serving over 1,000 users across four companies.
Research in Machine Learning: Created a novel dataset generator for skin lesion analysis and developed real-time anomaly detection algorithms, pushing the boundaries of AI.
Each role has been a stepping stone towards a deeper understanding of the technical aspects of software development. My goal is always to build software that every line of code not only functional but also impactful
